The azure-rumped parrot (Tanygnathus sumatranus) is a large bird endemic to Indonesia. It is found in Sulawesi and the Sangir Islands. It was previously conspecific with the blue-backed parrot, which is differentiated with its red iris and blue back versus the azure-rumped parrot's yellow iris and plain back. It is found in forests. Flocks are small and often active at night. Its main threats are habitat loss and trapping for the pet trade.
There are two subspecies: Tanygnathus sumatranus sumatranus (Raffles, 1822): Sulawesi. Sulawesi and nearby islands. Yellow iris. Tanygnathus sumatranus sangirensis Meyer, AB & Wiglesworth, 1894: Sangir Islands and Karakelong. More blue on wing bends and wing coverts, head darker green. Yellow iris
Previously, only sumatranus was recognized, but sangirensis was also recognized by the International Ornithological Congress in 2022 based on phylogenetic evidence. It is of medium size (32 cm), primarily green with yellowish edging to the wings, a blue rump, and blue wing bends. The head, mantle, wings and tail are darker green, the belly and collar are lighter green. It is sexually dimorphic, with the male having a red... Wikipedia →

Likely
About 40% of wildlife watchers report an Azure-rumped Parrot sighting in Tangkoko Nature Reserve on a given day, based on 32 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 26th most-seen of the 138 birds we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.
January and September
In those months about 50% of wildlife watchers report an Azure-rumped Parrot in Tangkoko Nature Reserve on a given day, against under 5% in February–March and December, the lowest months.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Azure-rumped Parrot sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Tangkoko Nature Reserve, in our data
Tangkoko Nature Reserve is the only park on Wallace's Line with enough records to rate Azure-rumped Parrot sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Psittacidae
The closest relatives of the Azure-rumped Parrot that you can see in Tangkoko Nature Reserve (family Psittacidae, New World and African Parrots) are Sulawesi Hanging-Parrot (about 40%), Pygmy Hanging-Parrot (about 20%) and Yellowish-breasted Racquet-tail (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Azure-rumped Parrot is recorded against all the birds logged in Tangkoko Nature Reserve (32 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
